You can count on at least one celebrity taking part in the XSport Fitness Rock 'N' Roll Chicago Half Marathon every year, whether it's performing on stage during the post-race party at Butler Field in Grant Park or running the course through the Loop and River North, among other neighborhoods.

“X-Men” star James Marsden, “Today” show weatherman Al Roker, “E! News” co-host Giuliana Rancic, Five For Fighting singer John Ondrasik and three-time Super Bowl winner Roger Craig all have run the race.

This year?

“Good Girls Go Bad” band Cobra Starship will perform and Craig and former “Bachelor” star Andy Baldwin plan to run the race. Former “Jon & Kate Plus 8” star Kate Gosselin ran the Rock 'N' Roll San Diego Half Marathon in June but said she will change things up a bit in Chicago and run the 3-mile version of Sunday's race — aka the Mini Marathon.

“I'm not one of those (lifelong) runners,” Gosselin, 37, said over the phone Monday. “I started running outside two years ago. It's an inexpensive workout I could do wherever and whenever. … Also, I get very little alone time, so it's my way to be by myself.”

In addition to Cobra Starship, the race features bands from various genres performing at each mile of the race, from classic rock and country to indie rock and Latin rock. Gosselin has her own race-day music playlist, as well as a few other traditions she's developing the more she races.

“The night before the race, I eat plain mashed potatoes for that carb load,” said Gosselin, who is running on behalf of couponcabin.com, a shopping website that hosts a blog she writes. “And the morning of the race, I eat a bagel with cream cheese. It's what I did before San Diego and it worked perfectly.”

Gosselin did achieve her goal of finishing that half marathon in fewer than two hours.
